:SPECIFICATION forming part of Letters Patent No. 625,03, dated May 30, l1.899.

Applicationiiled December 29, 1897. Serial No. V664,493.` (N0 model- 'Thisf invent-ion relates to coin-controlled vending-machines; and it consists in an' automatic device coni-rolled by the passage of the coin therethrough for delivering packages of -vendible `articles-such, yfor instance, as chewing-gum-wherein, if so desired, the same motor which produces the package-delivering operation actuates also an automaton.

In the drawings, Figure l is a perspeotire view of the whole device, showing the front thereof. Fig. 2 is a side elevation of the motor and its connections. Fig. 3 is an end elevation of the motor, showing the end of' the coin-chute. Fig. 4 is another end elevation of the same motor. Fig; 5 is. a vertical section through the machine on a plane situated between the automaton and the package-cow tainer as shown in Figi. Fig..6 is a vertical section through the automaton, showing the internal. operating connections thereof. Fig. 7 is a top plan of the motor and its connectious. Fig. S is a sectional view of the package-container, one of the sides being removed; and Fig. 9 isadetail view of the coinchute and a portion of the catch for holding the motor in check.

In -the drawings, A is the casing ofthe whole machine, and a is a transverse deck dividing the casing into an upper and lower compartment. In the lower compartment is the m otor,l1aving the spring-drum B,provided with a gear-wheel, as shown, which meshes with a pinion D' upon the Vdriving-shaft b, which operates the various connecting mechanisms. The driving-shaft b bears a gear wheel o, which meshes 'with the pinion c' upon a third shaft c. The shaft c bears a gear-wheel c", meshing with the pinion d' upon a fourth shaft d, carrying a suit-able fan dei vico (Z0 for regulating the speedpf revolution of the shaft o.' This particular arrangement of shafts and pinions is not essential in my device, but any,V automatic motor may he employed having a shaft arrangement suitable for cranks and cams, such as hereinafter described, and a governory or speed-regulator.

A coin-chute E is provided, which has an5 5 exterior inlet ori tice or slot e of suitable size7 to admit a coin of the 'required denomination.' This coin-chute leads to Vthe interior of the machine, and at its inner or discharge end is adjacent to the lever F, which is normally 6o held in a position to obstruct the passage of thel coin Xfromout of saidjchute.y The 1ever F is balanced or pivoted in any suitable manner, such as in the block f, and in order to retain the `lever in its normal position for obstructing the end of the coin-chute it is providedwvitha .spring F or counterweight F2, orboth. In the form shown the spring F' is fastened at one end to the-frame Y of` themotor or clock-movement, and the end f of 7o the lever is hooked through an eye f', Fig. 9, in the free end-of the spring, thus vpermitting a certain amount of free movement of the end of the lever before the springis put in tension, as hereinafter described. The other end of the lever f2 is also hooked4 and vextends to the fan do and is adapted to hook at such a position thereon that the weight of `the selected coin X pressing upon the lever as the coin issues from the discharge end of the chuteE will tilt the lever and release its end f 2 from the fan d0.

ln Fig. 3 the lever F is shown in full lines in its normal position for obstructing the'pas-Y sage of the coin X. The'weight of the coin in operating the lever F to a degree sufficient l to release the fan carries the end fo downward until it rests against the lower portion of the loop f', and in this position (shown in dotted lines in Fig. 3) the issuance of the coin I into the interior of the caseAis still obstructed, the tension of the spring F being sufficient to retain the' coin in the middle position. roo

"silion ot"` rest of the machine, llies a projection ero f of the lever F, which is on the same side oflthe fulcrum fas the counterweight F2.

When the machine is set in motion, however,l

'and the cam bw revolves in the directionV4 shown by its arrow, the projection f2? ofthe lever F israised by the action of the side f the notch b and the end f0 is loweredagaiust the tension of the spring F until the end fo takes a position indicated by the lowest dot-i ted lines in Fig. 3, whereupon the coin is pertions.

mitte'drto drop from the chute into the interior of the casing A. The rotation of the shaft b and cam blo continues until the position of the, cam is suchthat the projection f2 may again drop into the notch b, whereupon the .fan-arresterf2 ofthe lever drops into the position for stopping the movementl of the fan, which of course stops t-he motor.

Above the deck a is a vertical packagecontainer G, in which a column of packages Z.may be placed. Inv the normal position of rest of the machine the packages rest upon a block G', which is of la thicknessl equal to or 'slightly'less than the thickness of a package.y This block slides to 'and fro upon supports g',

andtheblock has attached to its lower side the upper portion of a U-shaped bend gm of va bent `wire whose ends g11 and g12 extend through perforations gl in the front and back of the package-container G and act as guides for the movement of the block G. When the package-container is moved in the direction of the arrow in Fig. 8 to the limit of its back? lward movement, a package drops down upon the supports g in front of the block, and when the 4block is again moved in a direction opposite to the arrowin said figure the lowermost,

package of the column is pushed'frorn under the remainder of the packages by the movement of the block and is forced out through an orifice g in the frontof the package-container. The package falls from the oriiic'e'g into a chute g0 and through an orifice go' in the front lof the casing A, as seen in Fig. 5, and-from said orifice it drops into-a retainer 902, having an outward opening 903, th rough which the package may be removed by the purchaser. On the end of the shaft b which is opposite the end bearing 'the cam b1 there is a crank Z112. This crank operates a pitman g2() by means of an eye Q21 on the end of the pitman of such size that there is a certainvalnount of playas between the crank and pitman, and hence the pitman is operated only when the crank is at or near two .opposite positions in its revolu- The pitman Q20 operates a bell-crank lever g3, pivoted, asl at Q31, to the deck a and extending upward within the casing of the.

package-container G and into a socket formed by the U-shaped bend gw, connected with the package-ejecting block G. As the crank Z112 revolves, the bell-crank g3 being in the posi-l A l,

tion of rest, as shown in Figs. 3 and 5, and the block 'G' being underneath the column of packages'Z, the block G is moved backward in the direction shown by the arrow in Fig. 8 until it is moved outfrom under. the'bottom of the column of packages Z and/ a package drops in front of said block.v By reason of the loose connection between the pitman g2"` and crank b12 a period of ,rest occurs at thisv position of the parts and the packages in the column have time'to settle downwardINAfter Ya brief period of lrest the continued rotation of the crank b12 opera-'tes to depress the p itman 92 and the bell-crank'lever and to eject a package from the oitice g of the packagecontainer. The position of the crank is so adjusted that when the fan-wheel is arrested by the fall of the end f2'of the lever F the block G remains under the column of packages Z. This arrangement is not essential, since the parts may as well be stopped in the other extreme position of the ejector-block G. I p'rovide, further,an automaton with means for producing movements thereof from the same automatic mechanism which causes the delivery. of the packages.

Upon the deck. e I place a vertical supporting-tubeK. This tube contains another tube K'. lhaving a flange 7.o', which rests'upon the upper edge of the tube K and is thus supported. Upon the upper end of the tube K I fix a movable part, as the head H0 of the automaton, which is pivoted to' the tube K', as by a transverse pivot h". An arm ho is attached tothe head H0, and this arm is `connected with a connecting-rod hoz, which passes downward through the tube K and into the lower compartment of the case A.

In theupper end' of the tube K, I also set an arm jo', which has al1 extension passing outward through the side of the. tube and so forms a pivotj), which continues as the' arm J 0 and hand of the automaton. The-arm jo' within the tube K is provided with a connecting rod joz, which passes downward Athrough the tube and out of the lower end thereof.

Uponsuitable bearings-as, for instance, in the motor-frame Y-are two rock-shafts H and- J, set parallelto the axis ofl the operat- IOO -IIO

ing-shaft b. These rock-shafts carry arms `h and j', extending toa point substantially under the tube K', and for convenience in or- .derto disconnect the parts the ends of the arms h and j are connected by links h"3 and 7'03 with the ends .of the rods 71,02 and j, re-

spectively. When the connecting-rod 7'02 is `pulled downward, -the arm J 0 of the automaton is raised to a position adjacent to the head H0 of the automaton, and when the connecting-rod rises again the arm J 0 drops back to itsformer position, thus indicating a gesture, such as a salute. hoz is moved upward by the movement of the .arm h the head H0 of the automaton is rocked upon its pivot h" and the automaton appears So, also, when the rod spectively,4 oth er .arms Hf and "J', extending in a diderent direction from the 4rock-shafts than the armsvh' and jf'and'are operated by mechanism in the motor carried, preferably,'

upnthe operatingfshaftb. zT-Uponthe shaft b is a cam b2, which in the normal position of rest acts upon the arm H'to'tiltthe rockshat't H and Vraise the-connecling-rod 71,02.

When the .shaft b revolvespthe free eniof.l

the arm H' drops off the raised' edge of the cam Z720 and in sodoing .permits a movement of the head H of the autor'naton.l The head is so set on its'pivot ho that it is-n'ot balanced thereon, but on being releasedtilts forward. Of Vcourse'the cam h2o may be used to operate' the device either as just described or to cause a positive inovementwof'the head from` a po.;

sition of rest. In the drawings the normal position of Vrest shows ther parts in the firstdescribed position with the arm H lifted and 'upon the raised portionvof the cam.

The arm J for moving the arm Jo ofy the automaton is actuated by a pin bo upon the side of the spurw'heel bo upon the shaft b. This pin in the revolution of the spur-wheel in the .direct-ion shown by its arrow-in Fig. 2

comes in contact with the free end of the arm J' and moves it, lifting the arm and pulling the connecting-rod J 02 downward, thus lifting the arm J 0 of the automatoml When the pin passes the end of the arm'J, theparts are cam bw is a crank Z280.

carried back by means of the weighted end of the arm Jl or bya counterweight in any other position.-.as, for instance, upon the army'.

Upon the same end of the shaft bo asthe extends' from this crank yand connects with au arm k1", extending radially from the.lower portion of 'thetube K". Astlle cam 530 revolves the tube K willthus be'tur'ned about .hand or arm J0 to make the salute, as men- The operation of the machine-is as follows;`

Alcoin of suitable size and-'weight' is inserted through the'slot e; rolls dQWnf-ishe.chute E,

strikes the arm Ffa'nd' movessaid arm far enough to releasiethe fan do from the action of the hook f2 of the lever F, thus starting the motor,- whereupon` the automaton immediately commences to turn in the direction` shown bythe arrow in Fig.`7. Soonyafter the motor begins to move the cam b1? liftsjtheflever Fun'til the projection f2" rides 'upo'the upper circular edge of said cam, thus depressl A connecting-rod 7cv'in-g-'th'e end-foand putting the'spring F uin-l dertension and releasing :the coin X by the depression offthe eudof the lever Fnpon .which ith'asvbeen -resting,^whereupon the coin .falls -intothe lower'compartment'iof the case A. When the motor starts, the bell-crank g3() moves theV block G backward and from under the column of packagesl, lwhereupon the column 'settle's down upon the supports g'.

automaton aboutits vertical'axis, the head of the automaton nods and the ldwermost 'package of thep Coluui'n is ejected, .falling into the chute g0 Vand then' `into lthe delivery-box 902, f

As the `motor,continues to Iac't, turning the .whenceI it-may be removed luy-.hand through 'g the opening 903 ill/leantime the automat-on has been turning about its vertical axis back "toits original position and its a'rm J o has been raised to produce the salute. The revolution of the shaftb continues, bringing the arms H', and J back to their original positions after producing the movements above mentioned,

and the cranks Z112 and b3 haare acted, respectively,to eject the package,as above described, p

and to return the automaton to lits original position facing toward thefront of the case A.

The cam blo, when the parts reach their nor- 'v mal position of rest, permits the projection f 20 to drop into the notch b of the cam by the action of the spring Fand of the counterweight F2, permitting 'the'end f2 to extend into the path of the fan do and to stop it, Whereupom the machine is ready for another operation. It will be noticed that the machine'is au'- tomatic throughout upon the `release of the motor by the action of the coin inserted through the slot e. Thel spring-drum Btcoutains a spring of suitable strength and length to permit many operations of the machine, and the number of possible operations thereof may always correspond to the number of` packages in the package-container G.
